Abstract

1,151,759. Optical sound play-back apparatus. SOC. INTERNAZIONALE FONOVISIONE S.p.A. 17 Oct., 1966 [18 Oct., 1965], No. 46409/66. Addition to 986,240. Heading G5R. In a pick-up device for sound reproduction comprising light production means linearly and angularly adjustable with respect to a mounting through a support on which the light production means and a lens are mounted, generally similar to the device described in Specification 986,240, a carrier for the light production means is in the form of a block 51 which is removably fixed in an opening 50 in the support 25a in rigid relation to the lens 26.
